Effect of cellulose nanocrystals content and pH on swelling behaviour of gelatin based hydrogel

In this research, a novel method was performed to obtain hydrogel with superior thermal stability by incorporation of cellulose nanocrystals (CNC) into gelatin based hydrogel. Glutaraldehyde was used as cross-linker due to its high chemical reactivity towards NH2 group on gelatin. Different ratio of...
